The 34-year-old newlywed took to Instagram Thursday to share a new photo of her adorable son Ace-- and he's gotten so big!
In the pic, the 14-month-old cutie is sporting a whale T-shirt, white shorts and a curly blonde 'do as he snacks on a chocolate cookie.
The mother-of-two recently talked about motherhood on Ryan Seacrest's KIIS-FM radio show, admitting that she's done having kids.
"Oh, we are done," she revealed. "I say we're done. I don't want to accidentally get pregnant one day and then that poor kid feels like it wasn't meant to be or something. We've got the girl and we've got the boy."
She also revealed she's been shutting down husband Eric Johnson a little bit more when it comes to 1:1 time between the sheets.
"Oh my gosh, yes," she said. "After four years, there are definitely moments where you say, 'No.' It's not like rejecting Eric as a man—it's just that one moment. I'm like, 'Give me five minutes.'"
Simpson is clearly loving married life, and she even joked about taking her husband's last name.
"Jessica Johnson. Doesn't that sound like the best stripper name ever?" she asked. "I did change it, but for everything else it stays the same. I guess I didn't change it on my Instagram or my Twitter, so does that not make it official?"
And if she were to make dinner reservations, which surname would she use?
"It depends on what restaurant it is. If it's a hard restaurant to get into, I will definitely say 'Simpson.' It helps a little bit," she confessed. "My license says 'Jessica Johnson.' That makes it legit."
Marriage and motherhood look good on Jessica -- don't you think!?
